At first my wife called her new cats Lavern and Shirley. But then our granddaughter, Sneaks, identified one as a male, so my wife decided on Agatha and Holmes. I told her that didn’t make sense. If one is named after Agatha Christie, the other should be named after Arthur Conan Doyle: Christie and Doyle. Or even better, Marple and Holmes; just don’t mix authors and characters! But my wife is confusedly insistent.
